Examples of Data Cleansing
Email List Cleaning: A company using email marketing campaigns has a large mailing list that includes thousands of subscribers. Over time, some email addresses become invalid due to reasons like account closures or typos. Data cleansing in this case involves identifying and removing these invalid email addresses, as well as duplicates and inactive subscribers, ensuring that the company’s emails only reach valid and engaged recipients. This results in improved open rates, click-through rates, and a reduced likelihood of being marked as spam.
Customer Database Purification: A retail company maintains a customer relationship management (CRM) system that contains customer data such as names, mailing addresses, phone numbers, and purchase history. Data cleansing in this example involves updating and standardizing the customer information in the database. This process includes correcting any misspellings or inaccuracies in customer names and addresses, merging duplicate records, and updating outdated phone numbers. A clean and accurate customer database helps the company in executing targeted marketing campaigns and enhances their communication with customers.
Social Media Analytics: A brand uses various social media platforms for promoting its products and engaging with its audience. The company collects data from these platforms to measure user interactions and analyze the performance of its content. Data cleansing, in this case, involves filtering out any irrelevant or inaccurate data (e.g., spam comments, bots) and aggregating data from different sources into a single, unified format. This ensures that the brand’s social media analytics reports are based on accurate and relevant data, which helps the company make better-informed decisions about its social media strategy.
